FRANK MALLOYE, OF SAN FRANCISCO, CALIFORNIA.

COMBINATION FRESH AND SALT WATER HYDRAN'I.

Specification of Letters Patent.

Patented Sept. 1, 1908.

Application filed February 18, 1908. Serial No. 416,577.

To all whom it may concern:

Be it known that I, FRANK MALLoYE, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented new and useful Improvements in a CombinationFresh and Salt Water Hydrant, of which the following is a specification.

The object of the present invention is to provide a combination salt andfresh water hydrant, in which nozzles shall be well adapted for theattachment of hose, either for fire purposes or for sprinkling, and inwhich it shall be impossible for the salt water to leak into the fresh.

In the accompanying drawing, Figure 1 is a side view, partly in verticalsection, of my improved hydrant; Fig. 2 is a cross sec tion thereof, onan enlarged scale, on the line 22 of Fig. 1; Fig. 3 is a similar view onthe line 33 of Fig. 1.

Referring to the drawing, 1 indicates the outer shell of the hydrant,forming a chamber which is divided by a central longitudinal or verticalpartition 2 into two compartments 3, 4, having the respective inlets 5,6, the compartment 3 being intended as a salt water conduit of thehydrant, and the compartment 4 as a fresh water conduit. The hydrant isclosed at the top by the cover 7, secured thereto by screws 8.

9 indicates the salt water nozzle and 10, 11, the upper and lower freshwater nozzles. The nozzles 9 and 10 are closed by caps 12, and thenozzle 11 is closed by a cap 13, which latter is formed with a smallnozzle 14, the cap for closing which is not shown, which latter nozzle14 may be attached to a small hose pipe for sprinkling or otherpurposes.

The escape of water from each of these nozzles is regulated by means ofa valve 16. Said valve comprises a stem 17, having a threaded part 18adapted to screw into a threaded aperture 19, which is formed in thevertical partition 2 and also in a horizontal tubular connection 20between said partition 2 and the side of the casing 1 of the hydrantremote from the corresponding nozzle. The outer part of said connectionis formed with a stuffing box 21, and is closed by a gland 22. The outerend of the stem is suitably conformed as at 23 to enable a wrenchapplied thereto to turn the valve.

The inner end of the stem is formed with a head 24, which is received ina socket 25 in the valve proper 16, an annular nut 26 around said stembeing screwed into said. valve 1.6 to hold the stem in place in saidrecess. Between the valve 16 and the seat 27 of the valve, is interposeda dishshaped washer or cover 28, of vulcanized fiber or similarmaterial, adapted to make a tight fit in the valve.

It is very important to prevent leakage of fresh water in the conduit 4.To positively insure this prevention, the tubular connections 20 areformed integral both with the outer casing l and with the partition 2,which connections completely inclose the stems of the valves, so that,if there should be any leakage between said stems and their bearing, thewater so leaking cannot escape into the other conduit. The constructionof the valvepermits of the use of these tubular sleeves for the valvestems, for it permits of assembling the valve, by, first, passing thestem 17 with the nut 26 thereon, through the nozzle into position in itsbearing, then lowering the valve proper 16 and the fiber cover 28through the top of the hydrant into position in front of the head of thestem, then inserting said head in the recess in said valve, and thenscrewing the nut into position, holding the head in place in the valve.

By providing means for securing the head in a recess in the valve, it iseffected that the valve stem can be turned, to move the valve up to, oraway from its seat, without turning the valve in its seat, thus avoidingwear upon the vulcanized fiber cover.

I claim 1. A combination salt and fresh water hydrant, comprising ashell or casing, a vertical partition dividing the interior of saidcasing into two conduits, a nozzle for each conduit, a valve for closingone of said nozzles, having a stem, and a tubular connection formedintegral with said partition and casing, through which said stem passes,substantially as described.

2. A combination salt and fresh water hydrant, comprising a shell orcasing, a vertical partition dividing the interior of said easing intotwo conduits, a nozzle for each conduit, a valve for closing one of saidnozzles, having a stem, a tubular connection formed integral with saidpartition and casing, through which said stem passes, a valve proper forclosing the latter nozzle, said valve having a recess, and a nut on thethe salt water from the conduit 3 into the stem of the valve and screwedinto the valve to hold the end of the stem in said recess, substantiallyas described.

3. A combination salt and fresh water said valve having a recess, a nuton the stem of the valve and screwed into the valve to hold the end ofthe stem in said recess, and 15 a cover of vulcanized fiber between saidhydrant, comprising a shell or casing, a ver: valve and its seat,substantially as described. tical partition dividing the interior ofsaid In testimony whereof I'have hereunto set casing into two conduits,a nozzle for each my hand in the presence of two subscribing conduit, avalve for closing one of said I witnesses.
